> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Data Types
> Reporter: Mehant Baid

> Due to the difference in the storage format of decimal data type in parquet
> versus the in-memory format within Drill using the decimal data type is not
> performant. Also some of the rules for calculating the scale and precision
> need to be changed. These two concerns will be addressed post 1.0.0 release
> and to prevent users from running into this we are disabling decimal data
> type by default.
